Another shooting incident in the United States has left two people injured in North Carolina, according to police officials.

The Charlotte-Mecklenburg Police Department said the shooting occurred at a nightclub in Charlotte on Saturday night, Press TV said.

Both victims suffered non-life threatening injuries and one of them was female.

"Two people were injured with gunshot wounds. One person drove themselves to the hospital and one person was transported by ambulance,” Charlotte-Mecklenburg Police Department Captain J.D. Thomas said.

Police have not arrested any suspects yet.

Several shots were fired, said police spokesman Rob Tufano.

The incident happened a few days after nine people were found dead after a shooting spree in Missouri.

Bodies were discovered at multiple crime scenes in a rural town in Texas County.

The suspected gunman was believed to be among the dead. The 36-year-old man was found dead of a self-inflicted gunshot wound in a parked vehicle in Shannon County, according to police.

A new study said gun-related casualties have turned into a “major public health problem” in the United States.

Eight US medical associations representing the majority of physicians published a "call to action" Tuesday that urges the medical community to study deaths and injuries caused by gun violence without "political influence or restriction” in order to reduce the health and public health consequences of firearms.

Each year, more than 32,000 people die as a consequence of gun-related violence, suicides, and accidents in the US, which is by far the highest among industrialized countries, according to the Centers for Disease Control and Prevention.
